Description
Technical field
The application belongs to valve field, and in particular to oblique flap valve built in a kind of high pressure.
Background technique
The shock of check-valves, water hammer are frequent occurrence.When the valve is closed, due to before medium is flow backwards, valve
Flap does not reach closed position and causes to hit；When valve opening, since the flap amplitude of oscillation is excessive, accelerating travel is long, also can
It causes to hit valve body.Tiltedly flap valve effectively overcomes swing check valve, lift check valve generates under this operating condition
Shock, water hammer can reach rapidly seating position since the range ability of flap is very short, to subtract to greatest extent
Small impingement phenomenon, and act gently, effectively realize its sealing and holding function.Slope clack tilting no-return valve is suitable for preventing
The horizontally or vertically reverse flow of fluids on pipeline, in vertical duct, or on the horizontal pipeline to any tilt angle between vertical.
Petrochemical industry adds the severity of hydrogen operating condition, and the shell leak source that is not allow for leaking need to be built-in structure, conventional oblique flap valve
It is external since structure limits, oblique flap-type structure built in this kind is developed by innovation.
Summary of the invention
The invention aims to realize oblique flap valve built in one kind, realize that valve body leaks without any built in pin shaft
Leak source greatly improves the overall performance of valve, is more suitable for the operating condition for adding hydrogen, LNG, nuclear power etc. harsh.
Summary of the invention: oblique flap valve built in a kind of high pressure, wherein including valve body, wherein valve body is hollow cavity, liquid
Body is flowed through from valve body, and flap is arranged in valve inner, and flap is in the closure state, is inclined in the runner of valve body, and
Realize the sealing to runner, flap is fixed on the inner wall of valve body by pin shaft and pin, and flap can be rotated around pin shaft.
Oblique flap valve built in a kind of high pressure as described above, wherein flap in the closure state, central shaft with
The angle of horizontal plane is 45 °.
Oblique flap valve built in a kind of high pressure as described above, wherein pin shaft, pin, straight pin, rocking bar are set in valve body
Frame, baffle, wherein baffle is fixed on body wall by straight pin, and rocking bar frame is arranged on baffle, pin shaft is arranged on rocking bar frame
And pin.
Oblique flap valve built in a kind of high pressure as described above, wherein top end of the valve body be arranged valve deck, sealing ring, washer,
Pendant collet.
The effect of the application is: the application can ensure that check-valves is built-in oblique flap-type, and opening angle is larger, inlet and outlet
The pressure loss is small, flow resistance coefficient is small, discharge coefficient is big, energy loss is low, avoids the problems such as backhand and shock.

Specific embodiment
As shown in Fig. 1, oblique flap valve built in a kind of high pressure, by valve body, valve seat, pin shaft, flap, rocking bar frame, valve
The part such as lid, sealing ring, pendant collet forms.Oblique flap valve is made of cylindrical shell and unitary rotation disk flap.Pivot
Axle position deviates valve body and valve seat plane in flap side.This structure makes flap be able to carry out pendulum model movement.Seal form is cone
Face and ball face sealing, valve seat and flap are all not in friction or sliding contact during combining and separating.Valve seat, flap and pivot
A totality is constituted, valve body import side is fixed on, its sealing and acting characteristic are realized by this structure.
Its working principle is that: the principal element that oblique flap valve opens and closes depends on the pressure of valve entrance end
Difference.When import end pressure is greater than the pressure of outlet end, flap is opened, and open degree is determined by the size of pressure difference.When out
When mouth end pressure is greater than import end pressure, flap is closed.When fluid is flowed into valve body by runner on the left of valve, in fluid thrust work
Under, portion's inclination flip including unitary rotation disk flap, runner is become larger, and stream is rented coefficient and is gradually reduced, and flow gradually increases
Greatly；When fluid stops flowing, the unitary rotation disk flap overturn can be closed in the case where its partical gravity is acted on and being fallen；Valve
Seat is in tilted layout in valve inner.The application can ensure that check-valves opening angle is larger, inlet and outlet pressure loses small, flow resistance coefficient
It is small, discharge coefficient is big, energy loss is low, avoid backhand and hit the problems such as.
Its assemble sequence are as follows: 1) valve seat is put into inclined valve body, and using welding and valve body firm welding；2) by flap
Rack-mounted with integral with rocking bar, and after being connected and fixed with pin shaft, whole to be packed into valve body, rocking bar frame and valve body are cast one convex
Platform plane is close to, and installs fix tightly on valve body boss using bolt with after finger setting；3) install again valve body middle chamber valve deck,
Sealing ring, pendant collet etc., last hanging bolt tense.
Compared with prior art, it is characterized in that:
The through-type valve body structure design of 1 high inclination-angle
Using the through-type valve body structure of high inclination-angle, for valve body using 45 ° of high inclination-angle designs, valve body middle chamber is at 45 ° with seat ring
Angle design not only substantially increases the trafficability performance of valve, more improves the operating characteristic of valve performance, inverse relative to tradition
Only 5 ° of inclination angle designs of valve, the high inclination-angle is through-type to be capable of providing bigger initial sealing than pressure, to generate very low pressure drop, and increases
Add the sealing performance of valve.In addition, 45 ° of inclination angle designs can also reduce the stroke during flap open and close, accelerates valve and open
It opens, closing velocity, is advantageously implemented the requirement of valve rapid-closing.The center of gravity of flap component is allowed to rotate to valve seat, therefore valve
The weight of valve always acts on valve seat, is allowed to always closely in conjunction with valve seat.
2. valve body middle chamber head and valve seat are inclined to two different angles.
45 DEG C of seat angle degree, valve body middle chamber head does not tilt same angle, using the different angle of inclination
Degree is 65 DEG C, does so the height that can not only substantially reduce valve body, can also reduce valve body head size, then guarantees performance not
Under the premise of reduction, the effect of cost can be reduced well.
The oblique flap-type structure of pin shaft built in 3..
Conventional swing check valve generallys use the shape that pin shaft hole gasket and plug screw formation sealing are directly played on valve body
Formula；The built-in oblique flap valve of pin shaft casts a boss at valve body middle chamber, and with inclination lumen at plumbness, then leads to
It crosses and increases a rocking bar frame structure, linked into an integrated entity with pin shaft and flap, then is by bolt that rocking bar frame is fixed in casting
Boss on, form built-in pin shaft structure, and then fundamentally prevent leakage caused by pivot structure.
